New York City Comptroller and Democratic mayoral candidate Brad Lander was arrested by federal agents at an immigration court after he tried to stop them from detaining a person. Lander was at the federal building in Manhattan, watching immigration court hearings. When agents tried to detain a man leaving a courtroom, Lander linked arms with him, asking to see a judicial warrant. The agents eventually separated them and arrested Lander. After his release, Lander said he was just trying to oppose Trump's immigration policies peacefully. This arrest happened while there's been a nationwide increase in many arrests outside immigration courtrooms. Lander's arrest has been criticized by other Democratic candidates and politicians.
